E-Mail Every three seconds, a new case of dementia is diagnosed somewhere in the world. The term encompasses a group of neurodegenerative diseases that have no cure and which affect memory, cognitive abilities and behaviour, and includes Alzheimer's disease. According to World Health Organization (WHO) data, it is estimated that dementia affects about 50 million people around the world. With increasing life expectancy and an ageing population, this figure is expected to increase to 75 million by 2030 and 132 million by 2050. Dementias cause disability and dependence, they have an enormous impact on those who suffer them and their caregivers, and raise considerable challenges for the sustainability of social protection systems. Although a number of drug therapies are available for treating the symptoms, psychosocial interventions help slow down the rate of progression and counteract the aspects that impair the quality of life of the sufferers and their caregivers. Through the eHealth Center, the Universitat Oberta de Catalunya (UOC) has launched a tool, called PSICODEM, that enables the best intervention to be chosen for each patient, depending on the dementia's severity and the aspects it is wished to address.
